Re: Mother Carrying Leg of Her Teenage Son After He Was Hit by a Police Car
The way I understand it is this: When you get a nasty cut in the femoral, the leg below the cut is now becoming oxygen deprived because all your blood is pooling on the sidewalk. Signals are sent from the leg to the brain, and the brain recognizes that something is wrong and it needs force the body to work harder. This is the concept of shock. The heart rate increases, vessels constrict, breathing becomes more intense - The body does everything it knows how to give the leg the oxygen it needs, and by consequence, ramps up production. Meanwhile, platelets work to close the wound. However, in amputation injuries, the nerves are severed, too. No signals to the brain from the leg requesting backup. The leg is on the other side of the interstate, brain can't help. So, the brain isn't all preoccupied with trying to save the leg, and doesn't start shunting blood to the area. This is my understanding, which is rather limited, but info on the reasoning doesn't seem readily available. But it's quite common for amputation injuries to have minimal bleeding. |

Re: Mother Carrying Leg of Her Teenage Son After He Was Hit by a Police Car
Of course - in the US, units with red-and-blue flashing lights are allowed to safely run red lights (emphasis on SAFELY), though many places are beginning to use the opticom system, which detects the presence of flashing lights and turns the traffic light green. Ambulances, firetrucks, and police cars are the big ones; but also rescue trucks, medic chase trucks, quick response squads, chief transport vehicles, and some (very very few) privately-outfitted vehicles. However, units with flashing yellow or flashing blue lights must obey traffic laws. Also.... Even though we don't always follow this rule, it is the LAW in all 50 states, sirens go with lights. If your lights are on and you are not stationary, your sirens should be on as well. But people are dicks and complain about sirens so we often turn them off, especially in residential neighborhoods. |

As with any investigation involving a cop causing related injury/death , The outcome will be the kid was threatening in nature to the cop , and it will be found to be a justified action by the cop resulting in no charges
